Application and Buying Notes

Before ordering, compare the part number DXS4045, the 12V system requirement, and the clockwise rotation with the unit currently fitted to the vehicle. Starter motors are sensitive to tooth count, mounting pattern, nose cone shape, and pinion location, so the 9-tooth design and 2-hole mounting arrangement need to match the existing application closely.

The listed dimensions are the best place to check if you are unsure. Measure the mount centre to centre at 132mm, flange diameter at 74mm, overall length at 202mm, and nose cone length at 42mm against the original starter. The M10x1.25 / 11 mount hole diameter and 30mm pinion diameter are also useful confirmation points when comparing units side by side.

This starter is described as Denso style and suits Denso applications, so matching the make profile matters as much as the electrical rating. The 1.0kW power rating, 9 teeth, and 8mm pinion at rest all need to align with the replacement unit to avoid installation problems or incorrect engagement. If the original starter is no longer present, the vehicle application and the physical measurements should be checked before purchase.

Warranty coverage is listed separately for passenger and commercial use, at 3 years and 1 year respectively. That makes it important to confirm how the vehicle is used, particularly if it is being fitted to a commercial application. As with any starter motor, correct identification up front is the safest way to avoid downtime, returns, and unnecessary removal work.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number DXS4045 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

OEX Starter Motor 12V 9Th CW Denso Style. Part number DXS4045 should be checked first. Listed voltage is 12. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number DXS4045, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a starter motor in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include HOLDEN NOVA, HOLDEN NOVA 1989, HOLDEN NOVA 1990, HOLDEN NOVA 1991, TOYOTA COROLLA, TOYOTA COROLLA 1981. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

Compatibility note: Confirm fitment by checking part number DXS4045, the Denso-style application, and the exact mounting and dimensional details before ordering. Vehicle listing references are helpful, but the starter should still be matched against the existing unit and application specifications.
